(Cl. .ffii-77)'4 4Q'Claims.

This. invention, relates; to a mecharsm. fon cleansing a suri'ace or surfaces in a single plane; The invention. relates more especially toA cleansing which. requires` the use. oi a liquid solvent or de ter-gent and' to. the.4 application of such-,liquidtoy a, surface to be cleansed by means of a rotating member such as. aA brush to. which liquid. is. supplied in the form of a fine spray.

More particularly, the invention may be used for removing from the inked faces of set-up type, electrotyped plates, foundry forms and the. like.

By way of example, the invention is hereinafter described as embodied in mechanism for cleansing the inked faces of set-up type ingall'eys.

In preparing type for printing, the typewhich is set up is transferred to galleys which consist. of shallow trays having ledges on both sides. and one end. The type is locked in the galley andi proofs are taken for the purpose of proof-reading for errors. it is then necessary to remove the ink from the impression faces of the type. When several galleys of type, have to be cleansed',V it is a troublesome and time-consuming job. Furthermore, when the type faces, are cleaned in the usual mannen inky cleansing liquid runs down between the pieces and lines of type and causes them to stick together.

It is an object of the .invention to provide apparatus which will apply sufficient cleansing fluid to the type faces for completely removing the ink but not enough to rundown, between the pieces. and lines of type. This. not. only avoids sticking. of the type but. also results in economical use ci the. cleansing fluid. Another object of the, invention is to. provide apparatus by which loaded, galleys: may4 be quicklyand easily cleansed withr a great saving of tiene or eiort. It isv a further object of the invention to. provide such apparatus with devices to safeguard it. against undesirable, operation.

For a moreV complete understanding oi the 1n.- vention, reference may be had to. the following. description of an embodiment. thereof, and to.. the drawings of which- Figure 1 is a front elevation of apparatus em.- bodying the invention.

Figure 9 is a. section on the line 9-9 of Figure 6.

The apparatus includes a main frame l on which is mounted an elongated trackway extending horizontally and' transversely inclined, i. e. laterally' tilted, as indicated in Figure 3, the angle oi" inclination being preferably about 70 from the horizontal. The trackway comprises essentially a pair of rails- U and. l.2the. lower rail l2 having` a flange i3 (Eiaurel) on its. lower edge tosupport loaded galleys placed on the. trackway. Such galleys are manually depositedin succession on the right-hand portion of the trackway, being leaned. against, the rails so that the type will not tall out, and aremoved toward theleit-hand end. by a. chain conveyor I4l whichpasses arounda pair of spree-kot wheels lo. and I8 and which includes a stretch on'the flange I3. Spa-ced lugs 2i! engage the galla-ys izo-ensure positive movement thereoi at a. predetermined rate when the conveyor'i's driven.. A typical galley is illustrated at 22 inv 2f, this galley having side ledges 24 and one end ledge 2.6. The matter or. bodyo type 28 is lockedin the lowerY corner ofl the galley by suitable furniture indic'zatedl at 3D. The length of the trackway illustrated ron the drawings is somewhat more than twice that of a galley so that the trackway Acan accommodate two galleys, one in thel starting position and one in the finishing position. Between these two positions is mounted a cleansing member such as a suitable cylindrical brush 32 for brushing the inked faces of the type as the gal-leys pass in succession. The .brush is mounted; on a'v rotatable shaft 34 journaled in a bearing' 35 mounted on the main frame l. The brush is preferablyl inclined so that the axis of f rotation is parallel to the plane of the trackway l2 but is inclined with, respect to. the direction of progress of the galleys along the track, as indicated in Figure 1,I and rotates in a direction contrary to the movement of the galley so that the brushing engagement with the type has a downward componentl toward the lower edge of the ed on the shaft 34 so that the brush is positively driven.

A common source of power, such as an electric motor 40, may be mounted on a platform 4|, carried by the frame I0, to drive both the conveyor I4 and the brush 32. The driving connections for this purpose are illustrated in Figures 1 and 3 and may comprise a shaft 42 connected to the motor 40 through a reducing gear indicated at 44. Mounted on the shaft 42 is a pulley wheel 46 which is connected by suitable belt 48 to a pulley wheel 50 on the shaft 34 to drive the brush 32. Also mounted on the shaft 42 is a sprocket wheel 52 connected by a driving chain 54 to another sprocket wheel 56 mounted on a shaft 58. The shaft 58 also carries a second sprocket wheel 80 which is connected by a suitable chain 62 to a sprocket wheel 84. The latter is mounted on a shaft 60 which drives the sprocket wheel I8 by means of a universal joint 68. The sprocket wheel I8 drives the conveyor I4. The sizes of the ferred, such switches being opened and closed by rocking the glass containers within which the mercury is sealed. Thus the switch |80 is controlled by rocking a lever |04. In like manner, the switch |02 is controlled by rocking the lever |05.

According to the present invention, the motor which drives the brush and the galley conveyor is automatically controlled, so that, when a galley is placed on the trackway, the motor automatically rstarts and continues to operate until the galley has been moved past the brush. To this end, a

" control mechanism is provided consisting of a bell foregoing sprocket wheels are selected in such a manner as to reduce the speed of drive so that the galleys are moved past the brush 32 at a suitable rate of speed considerably less than the peripheral speed of rotation of the brush itself.

During the rotation of the brush, a suitable liquid detergent, such as gasolene, benzene or an equivalent, is sprayed thereon to cut the ink on the type and to facilitate the complete removal thereof. To this end, a spray nozzle 'I0 is provided, this nozzle being supplied with cleansing liquid through a pipe 'I2 which leads to the nozzle from a suitable receptacle '|4. An air pipe 16 also leads to the nozzle from a suitable source of compressed air (not shown). The air is controlled by a valve operated by pressing on a Valve stem 18.

When the valve is opened, the air blast projects,

a spray of cleansing liquid along the brush in the manner indicated in Figure 4. 'Ihe nozzle is preferably adjusted to deliver a veryiine spray sufficient to moisten the ends of the bristlesyof the brush but not enough to deposit an excessive quantity on the type. In this manner, the objectionable infiltration of inky cleansing fluid between the lines and pieces of type isavoided. To confine the liquid spray to the brush 32, the brush is enclosed in a hood 80 which has an opening 32 toward the trackway I2. The brush has tangential contact with the type faces through the opening 82. The hood B0 also has a longitudinal boss 84 thereon which is open'as at 8G toward the nozzle 'I0 to receive the spray from the nozzle. The edge of the hood around the opening 86 is preferably bent in as at 88 V(Figure 4) to form a gutter to catch liquid which may collect on and trickle down the interior ofthe hood and to direct such liquid through a suitable tube 90 to a waste receptacle 9|. For the operation of the air valve. a solenoid 92 is mounted on the main frame I0, this solenoid having a movable core 94 supported by a spring 95 and connected through a cord or wire 96 to a rocking lever 98 which presses against the valve stem '18. When the solenoid 92 is energized, the core 94 is pulled down against the force of the spring 95 and the lever 98 is rocked to openthe valve and thus to operate the spray. When the solenoid 92 is deenergized, the spray valve closes.

Automatic means for controlling the operation of the motor 40 and the solenoid 92 are provided. Such means include a switch |00 for the motor and a switch |02 for the solenoid. In order to avoid re hazard through sparking at contacts, switches of the enclosed mercury type are precrank rockably mounted as at I| 2 behind the trackway, one arm of which bell crank is a trigger |I0 adapted to project forward between the rails I I and I2 and beyond the plane of the trackway, so that, when a galley is placed thereon, it leans against the rails and rocks the trigger H0 to the position illustrated in Figures 7 and 8. The bell crank has a second arm II4 which is connected to the switch lever |04 by an extensible link II6. The link |r|6 includes a pair of coaxial elements which may'telescope, or, as indicated in Figures 7 and 8, may comprise two sections of a rod maintained in alinement by a helical spring I8 which surrounds the sections and tends to draw them together. As a result of this construction, rocking movement of the trigger bell crank in a counter-clockwise direction, as it appears in Figures 7 and 8, results in a positive movement of the switch I 00 to the open position. A clockwise rocking of the trigger bell crank causes a pull on the spring II8 which closes the switch |00 unless such closing movement is opposed by sufcient force to extend the spring. In order to avoid opening vmovement of the switch |00 when the galley moves beyond the trigger II 0, a secondv trigger |20 is provided further along the trackway so that the switch |00 will remain closed until the galley is carried beyond the conveyor I4, the conveyor being then ready to receive another galley. Suitable rollers |22 may be mounted on the rail I2, as shown in Figure 1, to support the leading end of the galley as it moves off the conveyor I4. The triggers III) and |20 are operatively connected by a connecting rod I 26. A spring |28 is provided to pull the triggers toward the open-switch position so that the switch |00 is always open when neither of the triggers is engaged by a galley.

In the usual operation of the mechanism it is intended that, as each galley is delivered along the trackway to a position beyond the conveyor |4,.it will be at once removed by the operator so as to make room for the next galley which is being propelled along the trackway past the brush 32. In case the leading galley is not promptly removed, it is desirable to stop the machine before the next galley pushes the leading galley off the delivery end of the track. To avoid this diiculty, an auxiliary control device is provided including a trigger I 30 which is mounted on A a rocking lever |32 at the extreme delivery end of the trackway, the trigger |30 being in a position to be engaged by the leading end of a galley which has been pushed beyond the brush 32. Ihe lever |32 is connected as by a rod |34 to a n bell crank |36 which is pivoted at |30, the other crank |38 is thereby rocked as is also the switch 'lever |04. The rocking of the switch lever is in a When the trig- I direction to open the switch |66 and thus tol stop the motor 4D. Hence the rocking ofthe switch lever is against the tension of the spring M181 This increased tension on the spring H61 tends to rock the trigger I |0` in a counter-clockwiseV direction, and, if the spring tension were sufficiently strong, the trigger I I might pust a galley oi the conveyor. bility, the-free end of the rod |34 is slotted as at |42.V VWithin this slot rides a pin- Ilt on a latch |46, the latch being pressed hy a spring |48 so that it tends to swing to a position where it canhook onto a nose |56 on the arm |4'. Ordinarily the rod |34 holds the latch M6 in the position shown in Figure 7 so that there is no interference with the movements of the trigger I-I. If, however, the trigger is engaged so as toshitt the rod |343 toward the left, this permits the* latchi |46l to catch at once upon the nose so ast'o prevent counter-clockwise rocking of the trigger when the switch lever |66 is rocked by further movement of the rod |311 to open the svtch |00. Thus, when a galley reaches the end of the track |2,the motor which drives the conveyor IlI and the brush 32 is automatically stopped. Removal of the leading galley permits the trigger |36 to be pulled back to normal position by the spring II8, the parts thus resuming the positions illus trated in Figure 7.

It is desirable that cleansing fluid be supplied to the brush only when the brush is actually operating on type. To this end, a dual control for the solenoid 92 is provided, one control being responsive to contact with the galley itself and the other control being operated by contact with type in the galley. Thus the spray operates only during the passage of type past the brush, this being true no matter whether the galley is completely filled or onlyv partly lled with matter. Such control mechanism is illustrated in Figures 3, 6 and 9. The switch lever |96, by which the switch |62 is opened and closed, is operated through `a rod |66 which is connected to the end of the lever |62 rockable about a pivot |64. The connections are such that, when the lever |62 is in the position indicated in full lines in Figure 9, the switch |22 is open. When the lever |62 is in the position indicated in dotted lines, the switch is closed and the spray is in operation. Two elements hold the lever |62 in the openswitch position shown in full lines in Figure 9. Both of these elements must be moved out of the way before the switch |62 can be closed. One of these elements is a lever pivoted on the rail I I as at |66. The lower end portion of this lever |65 engages the high portion of a cam edge |68 on the lever |62 to hold the lever |62 against movement to close the switch |02. When the lever |65 is swung to the full-line position ind cated in Figures 6 and 9, it is then opposite the low portion. of the cam edge |68 so that it no longer obstructs the rocking of the lever |62 to close the switch |22. The lever |65 is swung by a trigger |16 which is engaged by the upper edge of a galley approaching the brush 32. This trigger is rockable about a pivot I'l2 and is connected to the lever |65 by any suitable means such as a link or rod IV.. When a galley strikes the trigger |16, the lever |65 is thus rocked against the tension of a spring so as to permit the lever |62 to rock in a direction to open the switch |62. A second control is provided, however, which prevents such rocking of the lever |62 until the type to be cleansed has reached the brush 32 so as to prevent premature actuation of the spray To obviate such a pessi-k CFI when the galley onlyV partly ril-led. with type.. The" second control is' in the formofa trigger |60? pivotall'y mounted as at |82 on the lower rail I2. trigger is engageable by the type itself and is provided? with ya nose |64- which is engaged by an end of the lever |62vso as to prevent rocking of the l'ever until the trigger |63 is rocked by engagement therewith of the type or matter inthe galley. Such rocking movement of the trigger is against a suitable spring |36 which tends to restore the trigger |39 to the kposition shown Figure 6 when not engaged by type in a galley. When the galley having matter therein is. started along the trackway by the conveyor l I4, the upper edge of the galley rocks the trigger If'l-I- soas to move the lever |65 out of the way ci the lever |62'. The body of type in the galley is customarily arranged as shown in Figure 2, that'. ifs, in the lower right-handcorner of the galley. Thus, as the galley advances, the type engagesthe trigger Il just before it reaches the brush- 32. The trigger |66 is recited to release thelever |22 which thereupon rocks under the influence of a spring |96 (Figure 9) thus closing the switch |92 and starting the operation of the spray lil. This rocking movement of the lever |62 to the position indicated by dotted lines in Figure 9 places the end portion of the lever under the nose |84 of the trigger |69, thus preventing reverse rocking movement of the trigger |80 by the spring |86 until the lever |62 has returned to its full-line position as shown in Figure 9. This is to prevent interruptions in the spray during the passage of the type body past the brush such as might otherwise be caused by gaps or indentations in the lower edge of the type body in the galley, against which the trigger |80 bears. Thus, in operation the engagement of the trigger |10 by the galley conditions the control means so that it is ready to close ther switch |62 as soon as it is released by the trigger |66. When the lever |62 is released, it locks the trigger |88) until the galley has passed the trigger |10 and the lever |62 has moved to open the switch |02. Thus the switch |02 is closed when the leading end of the type body engages and rocks the trigger |86, and remains closed until the trailing end of the galley itself passes the trigger |10. 'I'he spring Il| thereupon rocks the lever |65, the lower end of which rides along the cam edge |66 and rocks the lever |62 to open the switch |92. 'Ihe spray is thus stopped and the trigger nose |84 moves into position to lock the lever |62 in open-switch position. Thus the spray operates only when the type to be cleansed is opposite the brush. This avoids spattering of excess liquid on the unoccupied portion of a partly filled galley.
